Sure, sure.
Like I said, given your commercial (and closed-source) aspirations, I'm happy to consult on your project as a paid contractor. Doing work for free on a closed-source for-profit project is neither interesting nor in my interest.
And if you're not going to spell it out due to your morals, don't comment.
Nah, this isn't a moral issue.
I'm willing to do free labor for an open-source project (whether or not it's a commercial project), as that labor benefits everyone. I'm unwilling to do free labor on a closed-source project, as that labor only benefits the entity that owns the code. This goes double for a commercial closed-source project, because in that case I don't see a cent of the money that the code owner gets from my labor. [0]
If you think that wanting to get a piece of the fruits of one's labor is a moral issue, you have a very strange relationship with work.
